My kids love this book! Bought this for my daughter before she was born, along with the stuffed dog when they sold them at Kohls a few years ago. "GO, DOG, GO!" is also a command I tell our big dog when I want him to go somewhere! :)
Harry the Dirty Dog by Gene Zion is a classic wordless book. it is a book about a dog that hates taking baths. Since he hates them so much he decides to bury the bath brush in his yard and run away. When he runs away he gets dirty and very lonely. The story ends with him going back home and digging up his brush and getting a bath. This would be a good book to teach young students about good hygiene and the need to take baths/showers.
